Off-Grid Charging System, AA,AAA,C,D,9v

Original Article

The ultimate insurance to keep your low voltage gadgets powered while keeping your communications systems ‘up’ and running in situations ranging from a power outage to being at a remote location, is a combination of the proper solar photovoltaic panel, smart battery charger, and the right batteries.
The following suggested combination of equipment will provide ample charging for all of the typical consumer battery sizes (AA, AAA, C, D, and 9volt).
Most every typical consumer communications device will be powered by one of these battery sizes, OR, will have its own charger ‘base’ which itself usually requires about 12 volts or less (usually provided by a wall-outlet plug-in ‘brick’, but could be provided by a proper solar panel).
Portable AM/FM shortwave radios, flashlights, and 2-way portable radios are probably the most common gadgets to be used during disaster. Keeping them running will be crucial to staying ahead of the pack. With the proper adapters and know-how, you may also be able to keep your cell phone and laptop running – although their use may be limited if cell towers are out, etc…

Rechargeable Batteries

The right kind of rechargeable battery makes a big difference. The overall best price versus performance is the NiMH type battery (Nickel Metal Hydride).
Each size (AA, AAA, etc…) is available in various capacities, that is, how much power the battery will produce before it needs recharging. The higher the rating, the longer they will last (typically rated in mAh (milliamp hours). Example, a 2000 mAh rating will last longer than a 1400 mAh rating, before it needs recharging.

Battery Charger

It is very important to use a ‘smart’ charger. Not all battery chargers are in this class, but more and more are. To properly charge a NiMH battery requires a unique charging method and the proper sensing technology to know when to stop charging. Otherwise your batteries will not last long.
This ‘smart’ charger is unique in that in addition to plugging it in to a standard wall outlet, it can also run off of 12 volts DC and comes with a male lighter adapter for 12 volts DC.  This is the key feature that enables you to use a portable solar panel as the power source for the charger itself.

Solar Panel

Solar panels come in all sizes, shapes, and various electrical specifications. This particular solar panel is portable, folds up, and provides the correct output voltage x current requirements (watts) to power the charger listed above. It also comes with a female lighter adapter for 12 volts DC, and mates perfectly with the noted charger unit.

Putting it all together

With the three pieces of the puzzle listed here, the right batteries, the right smart charger, and the right solar panel, you will be assured of ‘free’ and unlimited charging of your battery needs for most or all of your consumer gadget devices, so long as the sun is shining…
It seems to me that this system would be great insurance for a disaster scenario where electrical power is lost for a time. Just a thought…

Food Storage Friday: Black Bean Hummus

Original Article

Black Bean Hummus Recipe



We've shared traditional hummus recipes with you in the past but when I came across this black bean hummus recipe I knew I had to share it with you.  I love hummus and I love sampling different variations of the recipe.


Black Bean Hummus (serves 8)


1 clove garlic
1 can black beans, drained (reserve liquid)
2 Tbsp lemon juice
1.5 Tbsp tahini
3/4 tsp ground cumin
1/2 tsp salt
1/4 tsp cayenne pepper
1/4 tsp paprika
10 greek olives (if desired)


Mince the garlic in the food processor.  Add black beans, 2 Tbsp reserved liquid, lemon juice, cumin, tahini, salt, and cayenne pepper.  Process until smooth, add additional seasoning and liquid to taste.  Garnish with paprika and Greek olives.


I don't have a food processor so when I make hummus, I always just throw all the ingredients into my blender and that works nicely.


Enjoy!
